' DEVICE Fox nsvu W-QQDEN o n invention relates to a device for leveling wooden floor sleepers shown in the accompanying drawin and more particularly v described in the f owing speci cation'and in laying wooden flooring upon a concrete "base it i'sessential that the floor sleepers to which the wood 'flooi'in is nailed should be 1130' 1y leveledci'n 0 er that thefloorin r m. ed to the sleepers may be on a horizonta sleeper, shown in cross-section, upon a rough floor level or base.

Fi ure 2 is an end elevation of the same ,and indicating a fragmentary portion of a sleeper supported in the device.

Figure 3 1s a view similar to Figure 1 with thesupporting screws reinserted in the oposrte side of the shoe that the latter may i e' adapted for a relatively wider ran e of adjustment for supportlng the vs eeper mounted vtherein. V

Figure 4 is an end elevation of the dev1ce shown in Figure 3 with a fragment of a sleeper resting thereon.

Fi re 5 is a vertical fragmentary crosssectional view through a floor sleeper, the concrete slab forming the rough floor level and also the concrete filling, poured between the sleepers. I

Referring now to the letters of reference placed upon the drawin s:

A denotes a rough oor level or slab of concrete. v

' B represents a wooden sleeper and C, a supporting shoe having a relatively deep channel portion C to receive the wood sleeper B to which the flooring is nailed.

E, E, indicate screws projecting through laterally extended flanges C, by adjusting which the sleeper may be raised or lowered as required to insure a level surface to supp gseretofore 1t has been customary to insert or wedges beneath the slee rs in order j that they may be properly 'leve ed upon the concrete bed or slab before the concrete fil'fing is poured between the sleepers to .the devel of t e top of the latter. It has therefore required considerable time and labor 5 a to properly lay-up the sleepers upon an even pane 7 before the concrete filling can poured between the latter, and the time represents a large proportion thus expended bullding ,a floor of this char- 85 The purpose of this invention therefore is to provide means whereby the sleepers may be xtuickly and easily leveled upon the concrete ase or foundation which means is adapted to be readily adjusted to provide an 4 even surface to which the floor may be I nailed.

A further object of this invention isto.

provide a device which is adapted for a relatively wide range of adjustment by the mere reversal of the supporting shoe with reference to the sleeper and by reinserting the supporting screws in the shoe.

A further object of this invention is to provide a device which is comparatively innsive to manufacture and at the same timesufiiciently strong for the purposes deith the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be made in the precise embodiment of the invention herein described without departing from the spirit of the same.

In the drawings accompanying this specification:

Figure l is a side elevation of the device u u it would ar when supporting a port the flooring.

C C designate flanges projecting downwardly from the bottom of the shoe between which the sleeper may be mountedas shown in Figures 3 and 4,when it is desired to provide for a greater adjustment of the sleeper than would be possible when mounted upon the screws as shown in Figure 1.

F, denotes a concrete filling poured between the sleepers level with the top of the latter,see Figure 5.

D represents a wood flooring nailed to the sleepers.

Having now indicated the several parts by reference letters the construction and operation of the device will be readily understood.

A rough floor level of concrete having been properly prepared, the sleepers B to which the wooden flooring D is afterwards attached,are supported in a plurality of the yoke-shaped shoes C, s aced apart throughout the length of the s eepers,-the workman then roceeds to adjust the sleepers by means of t e screws or bolts E so as to said bring the top of the wooden sleepers to a uniform altitude throughout the surface of the floor. The sleepers having thus been properly leveled, the concrete filling F is poured between the sleepers until it reaches a level on a plane with the top of the latter. The sleeper bedded 1n the concrete together with the sleepers. The wooden floor is then nailed to the top of the sleepers in the usual manner.

Having thus described my invention what I claim is:

1. A device of the character described comprising an element located beneath and adapted to support a floor sleeper and forming a seat for the same, said element extendin laterally from opposite sides of the said s eeper, and a plurality of adjusting screws projecting through holes tapped in the said element for regulating the altitude of the element with reference to a floor level,

screws proi'lecting upwardly and downwardly from t e said element, the upper portions of the screws being located at op posite sides of the sleeper and the lower portions of the screws forming supports for the element and the sleeper.

2. In a device of the character described, an adjustable single unit fitting located beneath and supporting a floor sleeper and having tapped holes extending through the fitting and a plurality of screws extending through the tapped holes of the fitting for supporting devices are thus emable screws or adjusting the altitude of the floor sleeper to a floor level, said unit connecting the screws at opposite sides of the floor sleeper and forming a seat for the latter, and the said screws extending above and below the said fitting, the upper portions of the screws being located at opposite sides of the sleeper; and the lower portions of the screws forming supports for the slee er and the fitting.

3. A device of t e character described comprising a unitary element of channellike form in cross-section adapted to receive and support a floor strip, said element having flanges integral therewith extending outwardly from its side walls to provide a relatively broad sup ort for the floor strip, and a plurality of adjustable screws projecting through holes tapped to said flanges for regulating the altitude of the device with re erence to a floor level.

4. In a device of the character described, a U-shaped shoe for supporting a floor sleeper having laterally projecting flanges tapped to receive supporting screws or bolts, adj ustbolts mounted in said flanges, said shoe also provided with ribs extending downwardly from the base of the shoe and spaced apart to receive a sleeper when reversed upon the supporting screws or bolts.

In testimony whereof, I sign this specification.

JOHN A. WHITTAKER.
